[SCSI] iscsi class: modify handling of replacement timeout
This patch modifies the replacement/recovery_timeout so it works more like the fc fast io fail tmo. If userspace tries to set the replacement/recovery_timeout to less than zero, we will turn off the forced recovery cleanup. If userspace sets the value to 0 then we will force the recovery cleanup immediately. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
